I received two e-mail from nortonsupport@norton.com talking about some number case of something I recent contact Norton to solve.
The thing is, I didnt contact Norton at least 3 months or more...
So looking well the e-mail there is a link to some different website, for that one: http://www.norton.xn--com-cn0a/
So that is the problem, it is fake e-mail from someone who wants to show themself as the Norton Antivírus.
So take carefull with that. The e-mail looks like the official Norton mail, layout and colors, everything very close to the official website, but it is an trap.
